“…However, the ocular comfort and dryness response encountered after 12 hours of contact lens wear in this study was similar to that widely reported as a common experience with different contact lens types. 3,13,18,19 The addition of other contact lens types to a crossover study design will run the risk of a higher discontinuation rate of study participants, which might influence the study outcome.…”

“…In a study of solution-induced corneal staining (SICS) in silicone hydrogel CL wearers, overall dryness and dryness at the end of the day were more severe in subjects who experienced SICS versus subjects without SICS [22]. Truong et al, found that inferior corneal staining was significantly associated with an increase in subjective dryness symptoms in silicone hydrogel CL wearers [23].…”

a b s t r a c tPurpose: To explore the relationships among length of contact lens (CL) wear, degree of corneal staining and severity of dryness symptoms, and to determine whether these relationships differ between Asians and non-Asians. Methods: Adapted soft CL wearers (n = 395; 180 Asian, 215 non-Asian) were required to discontinue CL wear for at least 24 h and report to the University of California, Berkeley Clinical Research Center (UCB-CRC). Fluorescein corneal staining was graded according to Brien Holden Vision Institute scales. Length of CL wear was reported by subjects and subjective dryness ratings were collected using the UCB-CRC Dry Eye Flow Chart (DEFC). Results: More Asian CL wearers exhibited corneal staining compared to non-Asians, and Asian CL wearers had a higher mean grade of corneal staining (p < 0.001), as well as a higher mean DEFC classification (p < 0.001). The difference between Asians and non-Asians in grades of corneal staining extent and depth were significant (p < 0.001). Among non-Asian CL wearers, dryness symptoms decreased with more years of CL wear and increased in the presence of corneal staining, which was not the case for Asian CL wearers. Conclusions: Asian soft CL wearers reported more severe dryness symptoms and demonstrated more severe corneal staining overall compared to non-Asians. Among non-Asians, dryness symptoms were less severe on average with increased years of CL wear and more severe in the presence of corneal staining. Dryness severity does not appear to be related to years of CL wear or corneal staining among Asians.

“…Even though the deterioration in ocular comfort was not significant, it was partly due to the increase in accumulation of deposits on the lens surfaces. The decline in ocular comfort could also be due to superficial punctate keratitis (SPK) stimulated by MPS used during 30-day lens wear (Diec et al 2012).…”

The purpose of this study was to determine ocular comfort level in subjects wearing hydrogel and silicone hydrogel contact lens wear for 30 days on extended wear basis. A total of forty-two contact lens wearers were recruited in this study. The comfort level of contact lens wearers was graded using Visual Analogue Scale (VAS) with scale from 0 to 100. Comfort level was graded at the first, fifteenth and thirtieth day of wearing, followed by an overall grading for each type of contact lens. The median comfort level achieved by hydrogel and silicone hydrogel was 80.00 with interquartile range of 26.25 and 21.25 respectively. No significant difference (p > 0.05) were found. Over time both types of lens wearing showed deterioration in comfort, which was also not significant (p > 0.05). Comfort level can be achieved with either hydrogel or silicone hydrogel lenses. The level of comfort is independent of lens material or oxygen transmissibility.
